WAGNER, onREMSEN', IOWA FASTENING DEVICE Application filed August 14, 1929. SerialNo. 385,952.

This invention relates broadly to fastening devices, and has as itsprimary object the V provision of a device of this character, es-

pecially adapted for use with chairs, and 5 especially designed for useas a complemental anchor or fastening member for securing two ointedmembers in interlocked engagement.

A still further object of the invention is to provide a fastening deviceor anchor of this character which will be found especially useful foruse with chairs for securing either the round of the chair in jointed orinterlocked engagement with the leg, or the legs of the chair in jointedor interlocked engagement with the seat of the chair.

A still further object of the invention is to provide a fastening deviceof this character consisting mainly, in an elongated rod or barformed'at one end with a prong or nailing member adapted to be driveninto either the leg or round of the chair depending upon the purpose forwhich the device is to be used, and at its opposite end the rod isprovided with either a similarly shaped prong or in lieu thereofprovided on said opposite end with threads whereby the said end of the.de vicemay be screw-threaded into the leg or seat of the chair,depending of course, upon the purpose to which the device is put.

A still further object of the invention is to provide a device of thecharacter abovementioned, which is simple in construction,

strong, durable, inexpensive, constituting! but 3 few parts, thoroughlypractical, reliable, and eflicient in operation, and otherwise welladapted for the purpose designed.

Other objects and advantages of the invention will become apparentduring a study of the following description taken in connection with theaccompanying drawings; wherein:

Figure 1 is a view partly in section and partly in elevation of a chairseat and leg. showing the same in jointed or interlocked engagement andshowing one embodiment of my invention applied thereto.

Figure 2 is a view partly in section and partly in elevation of a chairleg and supporting round, showing the application thereto of that formof the invention first illustrated in Figure 1.

Figure 3 is a perspective view of the fastening or anchoring device, themanner or use of which has been illustrated in Figures 1 and 2.

Figure 4: is a view similar to Figure 2, and showing the application ofa modified form of the device,

Figure 5 is a perspective view of that form of device used in Figure 4.

Figure 6 is a fragmentary side elevation of a chair leg and supportinground therefor, and showing the application of another form of theinvention.

Figure 7 is a perspective view of that form of the invention used inFigure 6.

Referring to the drawings, attention is first invited to that form ofthe invention illustrated in Figures 1 to 3 inclusive.

As shownin Figure 3, that'form of the device used in the figures justmentioned comprises an elongated shank 5, which shank may be ofcylindrical cross section and formed of any suitable durable metal. Atone end thereof the shank 5 is provided with a laterally disposed prongor piercing member 7 extending at right angles tothe shank. The prong orpiercing member 7 as shown comprises a shank 6 of substantiallyrectangular configuration in cross section and tapering longitudinallyto terminate in a substantially diamond-shaped piercing head or point 8,providing inwardlyfrom the free end of the member 7 oppositely extendinglateral shoulders 8 serving to secure the head 8 embedded in the Work,and thereby retain the fastener against lateral displacement relative tothe work. 7

At its opposite end the shank 5 merges into a point, and at its pointedend is suitably threaded to provide what may be termed a screw 9. 7

When using the device just described for securing a chair legto the seatthereof, it. will be seen, from a study of Figure 1, that the chair legL is in jointed or locked engagement with the chair seat S through themedium of the usual mortised joints. The prong 7 is hammered into theleg L adjacent the jointed end of the leg, the diamond shaped head 8insuring a positive gripping action of the piercing member with the leg.

The screw 9 of the member is screwthreaded into the chair seat S, withthe shank 5 extending parallel to the chair leg L.

When used as shown in Figure 2, that is, for maintaining the round R ofthe chair in mortised jointed relation with the leg L, the prong 7 isdriven into the round in the same manner as it is driven into-the. leg Lin Fig.- ure 1, while the screw end 9 is threaded into the leg L, theshank 5 lying in substantially a horizontal plane and parallel to theround Attention is now directed to Figures 4; and 5, wherein it will beseen that the device as therein illustrated, comprises a shank 5provided at one end with a piercing prong 7 similarin every detail tothe piercing prong 7 of the member shown in Figure 3. However,at-its'opposite end the shank 5 is laterally ofi'set as at 10 and isthen continued longitudinally to terminate in a piercing prong 11, thedetails of construction of which is in every way similar to the prong 7In: using. the-devices just described, a prong 7 is hammered orotherwise driven into the round R? which round is in mortised jointedengagement with the leg L of the chair. Prior-to which embedding of theprong 7 into said round R. the prong 11 is driven or otherwise passedinto the leg L, the offset portion 10 being imbedded in the leg, whilethe shank portion 5 extends into a suitable cavity or recess 12extendinglongitudinally of the round R.

Attention is now directed to Figures 6 and 7, and it-willbe seen thatthe device as illustrated in these figures comprises a shank 5" bentlaterally in the same direction at its opposite ends as at- 13, whichlateral directed end 13 terminates in piercing prongs 7", the saidprongs 7. being in every detail of construction the exact duplicate ofthe piercing prongs 7 and 7. A more detailed description of the prongs 7is therefore deemed unnecessary.

Thusit will be seen that the device as just described and clearlyillustrated in Figure 7 is of substantially U-shaped formation, the legsof the U constituting the prongs 11". In using this embodiment of theinvention, one of the prongs 7 is pierced or driven into the horizontalmember B! which may be the round'of a chair, while the other prong 7 isdriven into the vertical member L which may be the leg of a chair. Thusit will be seen that the shank 5 extends parallel to themember R alongthe side of the member for the greater length of the shank R", theremaining portion of the shank 5 extending transversely of the verticalmember 11".

From the foregoing then, it will be seen that .the device as illustratedin Figures 1 to 3 inclusive is especially designed and will be found themost desirable of the species for securing either the round of a chairto the leg of the chair, or the leg of the chair to the seat of thechair.

The forms of devices shown in Figures 5 and 7 could of course, be usedfor the same purpose as that form of'the invention illustrated in Figure3 however, these last described forms of the invention are best suitedfor various. andlsundry purposes, wherein a device of this nature can beemployed to advantage for securing any two jointed members in jointedengagement.

Even though I have herein shown and de scribed the preferred embodimentsof my invention, itis to be understood'that the same is susceptible tochanges fully comprehended by the spirit of the invention as hereindescribed, and the scope of the appended claims.

Having thus described my invention, what I wish to claim as new is:

1. A fastening device for securing two jointed members in their jointedrelationship, comprising an elongated resilient shank provided withthreads adj acentone end thereof for threadedly engaging oneof themembers and remote from said threads being provided with an integralprong extending at right angles thereto and terminating, in a spear headadapted to be embedded in the other of said jointed members.

2. A fastening device formedfrom a single length of wire. or likeresilient material and comprising aflexible shank having, a threadedtapered end, and remote from said end having a lateralprojection merginginto a pointed end and providedwith oppositely extending lateralshouldersinwardly from said pointed end.

3.. A, fastening device for. the purpose specified comprising a.flexible shank having. one end tapered and screw threaded, and at itsother end being bent laterally to provide a lateral projectionterminating in a spear head.

In testimony whereof I aflix my signature.

CHARLES B. WAGNER.
